INFORMATION REQUEST QUESTIONNAIRE

INSTRUCTIONS FOR COMPLETING THE QUESTIONNAIRE

I.  Introduction

This information request is to be completed for operations that comprise
the Aerospace Manufacturing and Rework source category at your facility.
 The Aerospace Manufacturing and Rework source category includes any
facility engaged, either in whole or in part, in the manufacture or
rework of commercial, civil, or military aerospace vehicles or
components.  Aerospace vehicle or component means any fabricated part,
processed part, assembly of parts, or completed unit, with the exception
of electronic components, of any aircraft including but not limited to
airplanes, helicopters, missiles, rockets, and space vehicles.

The North American Industrial Classification System (NAICS) codes that
describe facilities that may manufacture or rework aerospace vehicles,
components, or parts are listed in Table 1 below.  This table is not
meant to be exhaustive; facilities classified under other NAICS codes
may also be required to complete this information request if they
perform activities as defined above.

The reporting year for this information request is 2008.  If you cannot
provide 2008 data, you must contact Kim Teal of the U.S. EPA at
919-541-5580 or   HYPERLINK "mailto:teal.kim@epa.gov"  teal.kim@epa.gov 
prior to completing this information request to explain why 2008 data
are not available and obtain permission to submit data from another
year.

You must complete this information request for ALL manufacturing
operations that constitute aerospace manufacturing and rework at your
facility, regardless of whether the operations are presently regulated
under the National Emission Standards for Hazardous Air Pollutants for
Aerospace Manufacturing and Rework Facilities (aerospace NESHAP).  For
example, information must be submitted for the following operations even
though they are not regulated by the aerospace NESHAP:  chemical
milling, metal finishing, electrodeposition, composites processing,
manufacture of aircraft transparencies, and wastewater operations, among
others.  Additionally, you must submit information for operations that
may be exempted from regulation under the aerospace NESHAP including,
but not limited to, low volume usage coatings, activities associated
with the manufacture or rework of space vehicles, certain waterborne
coatings, certain cleaning operations, certain primer and topcoat
operations, and certain depainting operations.  Finally, you must submit
information where control requirements are not specified for operations
under the aerospace NESHAP, including the use of specialty coatings,
adhesives, adhesive bonding primers, or sealants.  

However, this information request does not apply to aerospace
manufacturing or rework operations that are regulated under NESHAP other
than the aerospace NESHAP, with the exception of halogenated solvent
cleaning.  For example, you should not include in your response
information regarding chromium electroplating operations regulated under
the chromium electroplating NESHAP.

You are not required to use the forms provided for your response,
although we encourage you to do so as much as possible.  If you have a
compelling reason to provide the requested information in another
format, you may do so.  For example, facilities that use a large number
of coatings and solvents may have existing spreadsheets or databases
that contain information equivalent to Forms C-1 and E-3.  You may
submit such spreadsheets or databases (or other forms of data) instead
of the forms provided.  In this case, please do not submit your
completed response using the upload website.  Instead, you should submit
your response by mail or email as described below.

All fields in the forms that apply to your operations must be completed,
even if you enter “N/A.”

For the purposes of this information request, all HAP concentrations and
emissions are to be quantified.  Do not report concentrations of
emissions as “trace” or “minimal.”  If a concentration is at or
below the applicable method’s detection level, then provide
information about the method (title and source), the calculated
detection level in units of the applicable raw material or emissions
concentration or mass rate, and the procedure for determining the
detection level.

Throughout these forms, many of the cells for your data input have
drop-down lists for you to choose an appropriate response.  If the
specific choice that characterizes your situation is not included in the
list, please select “other” and provide a description of your
situation in the comments section.

Form A-1.  Parent Company Information

Complete this form to identify the parent company of this facility. 
This information will allow EPA to distinguish small businesses in any
economic analysis that may be required.  Section I, Question 8 (size of
parent company) is an important factor that EPA will use to identify
small businesses.  Please note that the total of all full-time and
part-time employees should be reported.  This information is required
for the parent company, not just this facility, all facilities within
the parent company.

The Regulatory Flexibility Act (Public Law 96-354, September 19, 1980)
(RFA) requires consideration of the impacts of regulations on small
businesses.  The major purpose of the RFA is to keep regulatory
requirements from getting out of proportion to the scale of the
businesses being regulated, without compromising the objectives of, in
this case, the Clean Air Act (CAA).  If a regulation is likely to have a
significant economic impact on a substantial number of small businesses,
EPA may, to the extent allowed by the CAA, give special consideration to
those small businesses when analyzing regulatory alternatives and
drafting a regulation.  The Small Business Administration uses
employment ranges to separate businesses into "large" and "small"
categories.  The actual cutoff between large and small facilities is
dependent on the NAICS code of the establishments in question.  

Form A-2.  Facility Information

Provide the information requested in this form for this specific
facility.

Section I

In Question 1, provide the actual address (not the mailing address) of
this facility.  You must also provide latitude and longitude coordinates
for the facility.  Latitude and longitude must be reported in decimal
degrees to six decimal places.

Question 2 asks you to indicate whether this facility manufactures or
reworks aerospace components or parts.  If you answer “No” to this
question, please provide an explanation in the Comments section of what
activities are carried out at this facility and why you should not be
considered an aerospace manufacturing or rework facility.  If you answer
“No” then you do not have to complete any other parts of this
information request other than Forms A-1 and A-2.

Note that Question 2 is NOT asking whether the facility is subject to
the aerospace NESHAP.  If your facility performs any activities for the
manufacture or rework aerospace components or parts, you should answer
“Yes” to this question and complete the rest of the information
request.

Question 3 - Enter all applicable North American Industrial
Classification Codes (NAICS) that apply to the aerospace activities at
this facility.  NAICS codes may be found at   HYPERLINK
"http://www.census.gov/eos/www/naics/" 
http://www.census.gov/eos/www/naics/ .  Do not enter Standard Industrial
Classification (SIC) codes.

Question 5 – Answer “Yes” or “No” whether this facility
manufactures or reworks aerospace components or parts for each of the
listed market segments.

Question 6 – Enter the typical operating schedule for this facility
for the reporting year (2008).  You may provide estimates if you do not
track the hours/day and days/year the facility is in operation.

Section II

Provide the name and contact information for the technical contact for
your response to this information request.  The technical contact should
be able to answer inquires from EPA concerning any information provided
in your response.

Section III

Question 1 – Identify whether this facility is a major source of HAP
emissions.  Section 112(a)(1) of the CAA defines a major source “as
any stationary source or group of stationary sources located within a
contiguous area and under common control that emits or has the potential
to emit considering controls, in the aggregate,10 tons per year or more
of any hazardous air pollutant or 25 tons per year or more of any
combination of hazardous air pollutants.”

Question 2 – If you answer “No” to Question 1 of this section,
specify whether the facility has a federally enforceable permit
limitation to limit HAP emissions to less than the major source
thresholds and, if so, identify any such limits.

Questions 3 and 4 – identify any non-aerospace products manufactured
at this facility.

Question 5 – As part of this project, EPA may conduct air dispersion
modeling of the emissions from facilities that respond to this
information request.  This modeling requires the input of the maximum
hourly emissions from each emission point.  However, we realize there
are typically a large number of emission points at aerospace
manufacturing and rework facilities, and determining the maximum hourly
emissions from each and every emission point could be difficult and
burdensome.  Rather than asking for maximum hourly emissions for each
emission point, we are instead requesting that you provide a single
multiplier that we can use to scale up average hourly emissions (annual
emissions divided by 8,760 hours/year) to maximum hourly emissions.  We
understand that a single multiplier may not be applicable to all
operations at your facility.  Please provide your best estimate of a
multiplier that, overall, provides a general indication of the maximum
hourly emissions for your facility.  Based on the results of the air
dispersion modeling, we may at a later time ask you to provide more
specific information.    

We will determine average hourly emissions from the data you provide in
your response to this information request.  Therefore, you must provide
a response to this question, even if the multiplier you provide is 1. 
You must also provide a description of how you determined the multiplier
in the comments section of this form.

Form B-1.  Spray Booth Information

This form has space for entering data for 10 spray booths.  If you are
providing data for more than 10 spray booths, please add additional
columns as necessary.

Section I

Question 1 – Enter a unique identification number of your choosing for
each spray booth.

Question 2 – Choose one of the booth types from the drop-down list.

Question 3 – Enter the latitude and longitude coordinates for the
location of this booth.  The coordinates must be in decimal degrees to
at least 6 decimal places.

Question 4 – Enter the overall dimensions in feet of the building in
which the booth is located (not the dimensions of the booth itself).

Question 5 – From the drop-down list, select “Cross Draft” if the
airflow exits from the side of the booth, or “Down Draft” if the
airflow exits from the bottom of the booth.

Question 6 – For the reporting year, enter the average number of hours
per day this booth is in operation.

Section II

Question 1 – From the drop-down list, select the type of particulate
filter system used for this booth.

Question 2-3 – Enter the particulate control efficiency for the
particulate filters, and indicate how that efficiency was determined. 
The control efficiency should correspond to the coating operations
typically carried out in this booth.  For example, if a booth is
typically used to apply primer to small parts using HVLP spray guns,
then report the control efficiency that you believe best represents the
control efficiency achieved for the overspray generated by this coating
operation.  You are not required to perform testing to determine the
control efficiency.  Use your best judgment based on the information
available to you.

Section III

Question 1 – Enter the latitude and longitude coordinates for the
location of the exhaust stack for this booth.  The coordinates must be
in decimal degrees to at least 6 decimal places.

Questions 2-5 – Enter the diameter and height of the exhaust stack in
feet, temperature of the exhaust stream in degrees Fahrenheit, and the
flow rate of the exhaust stream in actual cubic feet per minute.

Section IV

Complete this section if this spray booth is vented to a control device
that reduces the amount of organic emissions.

Question 1 – Enter a unique identification number of your choosing for
this control device.  You must also complete a Form J for this control
device and the identification number entered here must match the
identification number entered in Form J. 

Question 2 – Choose the appropriate control device type from the
drop-down list.

Question 3-4 – Enter the capture efficiency for the organic emissions,
and indicate how that efficiency was determined.

Form C-1 and C-2.  Coatings

Use Form C-1 if you are reporting coating information in English units,
or use Form C-2 if you are reporting coating information in metric
units.  DO NOT complete both Form C-1 and Form C-2.

This form has space for entering data for 20 coatings.  If you are
providing data for more than 20 coatings, please add additional columns
as necessary.  You may group similar coatings together and report them
as a single coating, but the information you provide must be
representative of all the coatings in the group.

Section I

Question 1 – Enter a unique identification number of your choosing for
each coating.

Question 4 – Enter whether this coating is regulated under the
aerospace NESHAP.

Question 5 – If you entered “Yes” for Question 4 of this section,
select the coating type from the drop-down list.  The coatings in the
drop-down list are the only ones regulated under the aerospace NESHAP,
so you must choose one of these coating types if you entered “Yes”
for Question 4.

Question 6 – If you entered “No” for question 4 of this section,
then the coating is a specialty coating.  Choose the appropriate
specialty coating type from the drop-down list.  If you select
“other,” you must provide a coating type in the comments section.

Section II

Some of the information requested in this section, such as specific HAP
content, may be proprietary or undisclosed by the manufacturer.  You are
not required to perform testing to obtain the information to complete
this form.  Use readily available information from the manufacturer or
supplier such as material safety data sheets or product data sheets. 
You may also consider contacting the manufacturer or supplier to
determine if they can supply the requested information.  If you are
unable to obtain the requested information or believe that a coating may
have HAP constituents that are not disclosed, you may make a note of
this in the comments section. 

Question 1 – Enter the total volume of this coating that your facility
used for all coating operations (e.g., all spray booths) for the
reporting year.

Question 2 – Enter the requested physical property data for this
coating.  This information must be provided for the coating in its
as-applied condition.  Thus, multipart coatings and coatings that you
modify prior to application should be reported as-applied.

Question 3 – Enter the name of each HAP (organic and inorganic)
contained in this coating, the Chemical Abstracts Service (CAS) Number
for the HAP, and the mass fraction of the HAP in the as-applied coating.
 If you do not know the CAS Number, it is often provided on the material
safety data sheet for the coating.  You may also find CAS Numbers at  
HYPERLINK
"http://iaspub.epa.gov/sor_internet/registry/substreg/home/overview/home
.do" 
http://iaspub.epa.gov/sor_internet/registry/substreg/home/overview/home.
do .  There are also various other Internet sources that provide CAS
Numbers.

To avoid double counting, do not report the same HAP emissions under
different CAS numbers or as different compounds.  For example, do not
report both “total chromium” and “hexavalent chromium” for a
single chromium compound contained in a coating.  The correct reporting
method, particularly for chromium compounds, glycol ethers, and
polycyclic organic matter, is to report the specific compound (e.g.,
strontium chromate, ethylene glycol dibutyl ether) rather than the
general class of HAP (e.g., chromium compounds, glycol ethers).

This form has space for entering data for 5 HAP components of the
coating.  If this coating has more than 5 HAP components, please add
rows as necessary.

Section III

For each spray booth in which this coating was applied during the
reporting year, enter the booth identification number (must match the
identification number provided on Form B-1), and the percent of the
total usage of that coating applied in this booth.  The sum of the
percent usage by booth should equal 100 percent for each coating.  If a
portion of the coating was not applied in a spray booth, then the sum of
the percent usage by booth will be less than 100 percent.  In this case,
provide details in the comments section of the non-spray booth areas
where the coating was used including the latitude and longitude
coordinates, and volume of coating used in these areas. If your facility
does not maintain adequate records of the volume of coatings used by
spray booth, provide an engineering estimate and note this in the
comments section.

If a portion of a coating is applied outside of a spray booth, report
this under “Application of Coating Outside of a Spray Booth.” 
Select whether the coating is spray applied or other than spray applied,
and enter the percent of the total usage applied outside of a booth.

This form has space for entering coating usage for 10 spray booths.  If
this coating was applied in more than 10 spray booths, please add rows
as necessary.

Form D-1.  Chemical Milling and Metal Finishing Operations

occurs).

In Part B, please combine all of the fugitive solvent cleaning
operations in a single entry for each building in which fugitive solvent
cleaning occurs.  That is, for fugitive solvent cleaning operations, you
do not have to identify each individual cleaning operation.  Simply
combine all of the fugitive solvent cleaning emissions for each building
and report the requested information for that building.

This form has space for entering data for 3 cleaning operations (or
buildings for fugitive solvent cleaning).  If you are providing data for
more than 3 cleaning operations (or buildings), please add additional
columns as necessary.

Part A

Section I

Question 1 – Enter a unique identification number of your choosing for
each cleaning operation.

Question 2 – Enter the latitude and longitude coordinates for the
location of this cleaning operation.  The coordinates must be in decimal
degrees to at least 6 decimal places.

Questions 3-6 – Enter the diameter and height of the exhaust stack in
feet, temperature of the exhaust stream in degrees Fahrenheit, and the
flow rate of the exhaust stream in actual cubic feet per minute.

Question 7 – Enter the overall dimensions in feet of the building in
which the cleaning operation is located.

Question 8 – Enter a brief description of the purpose of this cleaning
operation (e.g., cleaning of aerospace components after machining;
cleaning to remove protective oils).

Question 9 - For the reporting year, enter the average number of hours
per day and days per year this cleaning operation is in operation.

Section II

Question 1 – Enter the name of each HAP (organic and inorganic)
emitted by this cleaning operation, the Chemical Abstracts Service (CAS)
Number for the HAP, and the annual emissions of the HAP from this
cleaning operation.  If you do not know the CAS Number, it is often
provided on material safety data sheets.  You may also find CAS Numbers
at   HYPERLINK

.do" 
http://iaspub.epa.gov/sor_internet/registry/substreg/home/overview/home.
do .  There are also various other Internet sources that provide CAS
Numbers.

To avoid double counting, do not report the same HAP emissions under
different CAS Numbers or as different compounds.  For example, do not
report both “total chromium” and “hexavalent chromium” for a
single chromium compound.  The correct reporting method, particularly
for chromium compounds, glycol ethers, and polycyclic organic matter, is
to report the specific compound (e.g., strontium chromate, ethylene
glycol dibutyl ether) rather than the general class of HAP (e.g.,
chromium compounds, glycol ethers).

Form E-4.  Halogenated Solvent Cleaning Operations

The EPA is requesting that you provide the information requested in Form
E-4 for all cleaning operations at your facility that are subject to the
Halogenated Solvent Cleaning NESHAP (40 CFR part 63, subpart T).  Even
though halogenated solvent cleaning operations are not subject to the
aerospace NESHAP, the EPA is concerned that some aerospace facilities
may have mistakenly reported emissions from these operations as
emissions from operations subject to the aerospace NESHAP in past
reporting to State or local agencies.  The EPA is currently evaluating
the residual risk from aerospace operations and halogenated solvent
cleaning operations.  In order to estimate the residual risk accurately
from each of these categories, the EPA is attempting to first develop
accurate emissions estimates.  Your efforts to properly report
halogenated solvent cleaning operations on Form E-4 and not on Form E-3
will play an important role in the EPA’s development of emissions
estimates for these two categories.

In order to assist you in determining which cleaning operations should
be reported on Form E-4, the following description is reproduced from §
63.460(a) identifying the sources subject to subpart T:

each individual batch vapor, in-line vapor, in-line cold, and batch cold
solvent cleaning machine that uses any solvent containing methylene
chloride (CAS No. 75–09–2), perchloroethylene (CAS No.
127–18–4), trichloroethylene (CAS No. 79–01–6),
1,1,1-trichloroethane (CAS No. 71–55–6), carbon tetrachloride (CAS
No. 56–23–5) or chloroform (CAS No. 67–66–3), or any combination
of these halogenated HAP solvents, in a total concentration greater than
5 percent by weight, as a cleaning and/or drying agent. The
concentration of these solvents may be determined using EPA test method
18, material safety data sheets, or engineering calculations. Wipe
cleaning activities, such as using a rag containing halogenated solvent
or a spray cleaner containing halogenated solvent are not covered under
the provisions of this subpart.

NOTE:  Not all cleaning operations that use methylene chloride,
perchloroethylene, trichloroethylene, 1,1,1-trichloroethane, carbon
tetrachloride, or chloroform are subject to subpart T.  Before reporting
a cleaning operation on this form, make sure that the cleaning operation
uses one or more of these halogenated solvents AND that the solvent is
used in a batch vapor, in-line vapor, in-line cold, or batch cold
solvent cleaning machine as these machines are defined in subpart T.

This form has space for entering data for 3 cleaning operations.  If you
are providing data for more than 3 cleaning operations, please add
additional columns as necessary.

Form I-1.  Startups and Shutdowns

This form is used to report startup and shutdown events that resulted in
excess HAP emissions AND that caused a NESHAP emission limit to be
exceeded or caused a deviation of any requirement of the NESHAP.  Each
aerospace manufacturing and rework operation that emits HAP and each
add-on control device used to reduce the emissions of HAP from aerospace
manufacturing and rework operations is subject to reporting on this
form.

For the purposes of this form, particulate filters and waterwash systems
used to capture overspray in paint spray booths are considered to be
add-on control devices.

The following examples are provided as guidance for which startup and
shutdown events must be reported:

Example 1:  A facility has several spray booths in which aerospace
primers and topcoats are applied.  The ventilation fans on each spray
booth are shut off when the booth is not being used and turned on again
when parts are ready to be coated.  No coating is applied when the fans
are not operating.  Even though each time the fans are turned on and off
is a startup or shutdown event, Form I-1 does not need to be completed. 
Because no coatings are applied when the fan is not operating, emission
limits would not be exceeded during the startup and shutdown events.

Example 2:  A facility uses a thermal oxidizer to meet the 81 percent
organic HAP emission reduction requirement of 40 CFR 63.745(d) for
aerospace primer and topcoat operations.  The thermal oxidizer has been
shut down for maintenance.  Following the repairs, the thermal oxidizer
is restarted from a cold start, and the facility immediately starts to
apply primers and topcoats.  The emissions while the thermal oxidizer
was not at the operating temperature resulted in an exceedence of the 81
percent emission reduction requirement.  This event must be reported on
Form I-1.

Example 3:  A facility applies primers containing hexavalent chromium to
aerospace parts in a spray booth.  One operator turns off the
ventilation fan for the spray booth, but another operator is still in
the booth applying the primer.  This shutdown event must be reported on
Form I-1.

Provide the requested information if it is readily available.  You are
not required to perform additional testing or data gathering for these
events in order to complete this form.

Form J-1 to J-10.  Air Pollution Control Devices

Complete the appropriate form for each air pollution control device that
you use to reduce HAP emissions from aerospace manufacturing and rework
operations.  You are not required to complete these forms for
particulate filters and waterwash systems used to capture overspray in
paint spray booths.  Spray booth particulate filter information is
reported on Form B-1, Section II, Particulate Filters.

Concerning mechanical collectors and fabric filters reported on Forms
J-3 and J-4, if these devices are vented within a building, leave the
latitude and longitude entries blank and note in the comments section
that the device is vented within a building.  Include an identification
of the building in the comment.

Provide the requested information on these forms if it is readily
available.  You are not required to perform any additional testing in
order to complete these forms.

Form K-1.  Air Pollution Control Device Costs

Complete this form as completely as possible using readily available
information for each air pollution control device for which you
completed a Form J.
